Hi. I noticed a couple errors…
On file fields, you have the wrong field name prefix. the field tag is my_fluid_field but your image tag says fluid_field:my_image without the my_ prefix of the field name.
Some earlier example of displaying multiple fields uses the fluid_field field name. might be good to be consistent with all the examples.
RTF Text and Textare Fields: Textare should be Textarea
